I'm not sure that reasoning holds. Rejecting all email from senders which haven't sent anything before with a "service unavailable, try again in X minutes" is, theoretical anyway, covered by the mail transport protocol. Obviously this won't get rid of spammers who in fact do try again in X minutes, but it does get rid of rubbish from worms etc which lack more sophisticated retry mechanisms. It also gets rid of the vast majority of spammers who don't bother to retry. I'd expect that to change though as soon as it's making a noticable dent into the spammers' success. Still more time for the filters to catch up... Volker -- Volker Kuhlmann is possibly list0570 with the domain in header http://volker.dnsalias.net/ Please do not CC list postings to me.
